Access unrestricted remote desktop from very restricted office network (lemmy.world)

I want to access an unrestricted desktop at home (preferably a docker novnc desktop container), from the very restricted office laptop/network.

The foundations are clear, started a docker container with novnc access published the porst, forwarded the required ports on my router, and i can access it from outside using my phone, or my own laptop, but can't from the office.

The novnc landing page loads, but the connection to remote desktop fails, probably because the websockets connections are also blocked in office, so only the plain http(s) accesses are allowed (not even RDP is allowed).

(Not even dyndns providers are allowed, but i can note my current ip address in my phone :D )

Ofc i barely can install anything on office laptop, so i can create fe openvpn tunnel, etc...

Do you have some hints if it can be solved?

You can setup Apache Guacamole on your server. It uses Websockets by default, but it also has an automatic fallback to plain http/https. It will be ultra slow, but at least it will be working. It will behave like any other website, so no security risks for your company if they already have a proxy server to monitor your Internet traffic.

Was about to post to use Guacamole too, web sockets will work over HTTPS, OP is likely trying to do websockets over another port that's getting blocked.

But over HTTPS with Guac should be fine because I did this exact thing on a very locked down work network

Some proxies block Websocket Connections by default for unknown URLs, even for port 443. Don't ask me how I know :D
